When does a foundation need repairs?


When Does a Foundation Need Repairs?


Some signs that indicate foundation problems include:

  • Excessive slopes in the floors

  • Cracks in the brick or sheetrock (cracks do not always mean repairs are needed)

  • Doors that are out of alignment

  • Doors that do not open and close correctly

If you think there may be a problem with your home's foundation, the first step is to have your home inspected by a professional engineer.  An independent engineering firm, like Isbon Engineering & Associates, will provide you with an unbiased evaluation of your home's foundation.


Our firm is not associated with any foundation repair company or contractor. We do not take referral fees from any contractor that would bias our opinion.


We perform an elevation survey and use this along with exterior or interior signs of movement in order to properly evaluate the condition of the foundation.


If the slopes are excessive and greater than 1 inch in 10-15 feet along with exterior/interior distress, then underpinning could be required if the home has settled. We normally do not recommend that underpinning be performed if there are not slopes and only cracks. We do not recommend installing piers under a heaved area of a foundation unless the complete foundation is piered. A foundation that has excessive sloping, along with other signs of distress, could be in need of repair.  Underpinning is the most common type of repair.


Underpinning a foundation is performed using piers.  The piers are used to provide support for an area of the foundation that needs to be raised.  The four main types of piers used in underpinning are drilled concrete piers, concrete pressed pilings, steel piers and helical piers.  The type of soil under your home and the type of foundation determines which pier should be used.


Drainage corrections also at times are recommended to correct foundation issues. Our evaluations always review the drainage of a home. If the soil does not properly slope away from the home, the foundation can heave or settle depending on the soil properties. We many times make recommendations for a french drain or surface drains to help correct foundation performance issues.


Another type of common problem with a foundation is trees close to a home. Many people think that trees cause a home to lift up because of the tree roots, in fact they normally cause a home to settle. The tree roots grow under the foundation and remove moisture from the soil and can cause it to shrink and settle. This can result in the foundation settling. Root barriers are commonly recommended between the trees and the home. Installing a root barrier stops the roots from growing under the home and drying the soil.


If you think you may have a problem with your foundation, or just want to know the condition of your foundation for peace of mind, please call us for an inspection.
